DOUBLE-HOPPER-BOTTOM CAR.

SPECIFICATION forming part of Letters Patent No. 664,760, dated December 25, 1900.

Application filed August 17, 1900. Serial No. 27,162. (No model.)

To @ZZ whom t 'mfr/,y concern:

Be it known that I, GEORGE I. KING, a citi-V ren of the United States, residing at the city of Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Double-Hopper-Bottom Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which Figure l is a vertical section al View through one end of my improved car. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevational view. Fig. 4 is a top plan view of the framing of the car; and Fig. 5 is a vertical cross-sectional view on line 5 5, Fig. 4.

' This invention relates to a new and useful improvement in car construction, and particularly to the underframing, and while eutitled a double-hopper-bottom car77 it will be obvious that my improved nnderframing can be employed in connection with other types of cars-such, for instance, as gondola, box, and dat cars, or cars wherein a single hopper is used.

The special features of this present invention reside in the provision of strengtheningplates upon the side sills, which plates preferably extend beneath said sills, or it is obvious that said plates may extend above the sills, said plates continuing substantially from support to support of the car-framing. These supports are usually in the form of body-holsters, and the ends of the strengthening-plates shown in the accompanying drawings are secured directly to the ends of said bod y-bolsters. The center sills are also preferably provided with strengthening-plates which extend therebeneath, producing substantially plategirders- In the instance of the plates for the center sills their lower edges are provided with tension-anges, while with the plates which are secured to the side sills an angle may be riveted on their lower edges, said angle forming the tension-flange of this side structure, which is substantially in the form of a plate-girder.

Another feature of my invention consists in forming the side sills of parallel angles,

said side sills thus being made extremely light, enabling the lower member to be cut oli` slightly within the lines of the Vbody bolsters or supports, the upper member of the side sill preferably extending throughout the length of the car. The two members which constitute the side sills have their flanges preferably presented inwardly.

I do not deem it necessary to describe in detail the various parts of the car shown in the accompanying drawings, and will therefore direct my description chieliy to those parts and combination of parts which I deem new.

l indicates the center sills, which are preferably channels with their flanges presenting inwardly. To the outer faces of these center sills are riveted plates 2, said plates being formed deepest at their middle portions and having their ends inclined coincident with the inclined floors at the ends of the car. These plates 2 form the inner hopper-walls and have their lower edges ianged inwardly, as at 3, (shown in Fig. 5,) these inwardly-extending flanges forming the tension-flanges of a plate-girder made up of the center sills and these plates, the compression-flange of each girder being formed by the upper flange ofthe center sill to which the plate is attached.

4 indicates the body-bolster, and 5 the upper member of the side sill, which member preferably extends throughout the length of the car, being attached at its ends, as are the center sills, to the end sill 6.

7 indicates the other member of the side sill, which is attached to the end sill and arranged parallel to the member 5. This member 7 is also secured to the body-bolster, but terminates a short distance beyond said bodybolster. Lattice -bars 8 may be employed between these parallel members of the side sills for the purpose of giving them strength.

9 indicates a plate made deepest at its middle portion, said plate being secured at its ends to the body-holsters and throughout its upper edge to the upper member 5 of the side sill. The shallow ends of the plate are also preferably secured to the inner ends of the lower member 7 of the side sills, as shown in Fig. 3.

l0 indicates an angle which is preferably arranged on the inner face of the plate 9 and IOO along the lower edge thereof substantially throughout the length of said plate, said augle being bent to conform to the shape of the lower edge of the plate.

By this construction it will be seen that the side sill of the car outside of the body-holsters consists of parallel members strengthened by lattice-bars, if desired, one of said members extending throughout the length of the ear and forming the top ange of a plate-girder, the web of which is secured to said side-sill member and to the body-bolster, the lower edge of said web being provided with a flange in the form of an angle riveted thereto, said angle forming the tension-Hange of the plategirder, while the upper member of4 the side f sill forms the eompression-iiange of said plategirder. This construction is extremely strong and rigid and is sufficient to carry the vertical load between lthe bolsters or points of-support.

It is obvious that instead of having the member 7 at the side'sill formthe top flange of the plate-girder the member 5 can be continued throughout the length of the car, (said member 7 being cut short,) said member 5 fforming the tension-ange of the plate-girder Vand being arranged at the lower edge thereof,

while the angle l0, arranged at the upper edge ofthe plate-girder, would form the compression-flange of said girder.

Having thus described my invention, what I claim, and desire tolsecure by Letters Patent, is-

l. In a car, the combination with-the bodybolsters, of an angle extending throughout the length of the ear and forming aside-sill member, said angle being secured t-o the ends of the holsters, a web-plate also secured Vto 'the ends of the holsters-and having one edge edge of said web-plate and forming the ,teilsion-ange of a plate-girder structure, of which the angle 5 is the compression-ange; substantially as described.

3. In a car, the combination with body-bolsters, of an angle 5 extending throughout the length of the car and secured to the ends of said bolsters, web-plates 9 which are deepest at their middle portions and which are secured to the ends of said body-bolsters, and to said angle 5, an angle l0 secured to Athe lower edge of said Web-plate, and Vertical posts secured to said plate; substantially as described.

4. The combination with body-holsters, of plate-girder side sills consisting of angles 5 and 10 and the Web-plates 9, the ends ofsaid vWeb-plates being directly attached to theends of the bo'lsters; the center silis, andthe plates 2; substantially asdescribed.

5. The combination with the center sillsyof Vthe plates 2 secured thereto and provided with flanges 3 at their lower edges, the body-bolsters 4, the angles 5, the end sills towhich said angles 5 and thecenter-sills -are-cenneet-ed, the angles 7 parallel to the-angles 5, the web-plates 9, and the angles lO-seeured to the lower edges of -said plates 9; `substantially as described.

6. In a car, the combination With the bodybolsters, of a sidesill consisting of fparallel angles at the ends of thecar, oneof-said angles extending throughout the length of the car, and the others terminating a shor't distance inside of the bolsters,a plate secured to the continuous angle, to the inwardly-'prod
